MInIne-Macmnn.

To all whomiit may concern:

Be it known that I, WILLIAM a citizen of the United States, and residentof Union-town, in the county of Fayette and- State of Pennsylvania, haveinvented a new and useful Improvement in; Mining-Mas chines; and I dohereby declare the following to be a full, clear, and exact descriptionthereof. r V

My invention relates to minlng machlnes.

The object of my nvention is to provide 7 a simple and efficient form ofmimng'ma- "chine in which. the coal maybe mined rapidly andexpeditiously, doing away with the hand-operations now commonly employedin the mining of coal with the pick and shovel."

To these ends my invention comprises the novel features hereinafter setforth and claimed.

In the drawings, Figure l is a planview of my improved mining machine;Fig. 2 is a side elevation; and Fig. 3 is a detail of the frame forshifting the picks.

Referring to the drawing, the numeral 2 designates a suitable truckmounted on wheels 3 adapted to travel on the track 4, which is laid onthe floor of the mine.

Mounted forwardly of the truck 2 is the frame 5, said frame beingcomposed of the side bars 6 which have the forwardly and the frame forthe-purpose more fully hereinafter set forth. At the forward end of theframe 5 are the casters or wheels 15 which support the forward end ofthe frame when the machine is in operation, said casters traveling onthe floor of the mine beyond the track 4. In

order to raise the I a Specification of Letters Patent.

and lift the casters 15 from the floor mine, provide the latch hooks 16which of the truck 2, said latch hooks being connected by the rod 17 soas to be capable of being operated.

in unison. An operating rod 18 is connected as to the rod 17 and saidrod 18 is connected to the lever 19 whereby the latch hooks are movedinto and out of engagement with the cross-bar 10. It is apparent fromthe above that the cross-bar 10, the forward end of the frame will beelevated so as to lift the casters from the floor of the mine when themachine is being. transported on the track 4 from. a r

one part/'ofthe mine to another.

A. suitable electrical motor-'20 is mounted a on the frame 5 which hasthe bevel-wheel I 22 which meshes with the bevel-gear 23 on thestub-shaft 24. A sprocketwheel 25 on the stub-sh'aft24 is'engaged by thesprocketto chain 26. This sprocket chain 26 engages a sprocket-wheel 27on the vertical shaft 28 journaled in bearings in the members 7 and 8 atthe forward end of the frame 5.

30 on the stub-shaft 24 15 A gear-wheel meshes with a gear-wheel 31onthe stubshaft 32. Stub-shaft 32. carries the sprocketwheel 33withwhich the chain 34 engages. The chain 34 also engages a sprocket wheel35, on the vertical hearings in the members 7 and 8 at the opposite sideof-the frame 5.

At the forward end of the frame 5 are the tringular shaped chainguides39, said guides being supported by the. standards 40 to the frame 5. Theverp and 40 secured tical" shafts 28 and 36 pass through the triangularchain-guides 39 and have the cutter chains 41 mounted: on

sprocket wheels 42, 43 and 44 at the corners 9 of said guides, sprockets44 being secured to said shafts, said cutter-chains having suitablecutters 45. These cutter-chains are driven by power transmitted from themotor through the s arranged at difi'erent' e made into the wall of atsuch difierlcnt heights. Y

er the a when the latch hooks engage to.

shaft 36 journaled in 80 said guides rocket-chains 26 and 34, and Saidchains ei heights, cuts will 'of the double Mounted on theframe 5 is thepick-frame 46, said frame having the rearwardly extending 'bar 47resting on a fulcrum at 48 on the cross-bar 9. The rear end of the bar47 passes through the clevis-member 49 and the pin 50 supports said barin said clevismember, a number of holes 51 providing for the adjustmentof the bar at different heights so as to change the angle of inclinationof the picks as hereinafter fully set forth.

A multiple double crank-shaft 52 is journaled in bearings 53 on theframe 5, and said crank-shaft is driven (by power transmitted to thesprocket 54 by means of a chain 55 passing around the sprocket 56 on theshaft 57 which is driven by a suitable motor 58. The picks- 59 aremounted to reciprocate in guides 60 in the frame 46, the inner endsofsaid picks being connected to 'pitmen 62 crank-shaft so that said picksalternate with each other in advancing and withdrawing from the coal.These picks, as

shown in Figs. 1 and 3, are secured to a box-like member 61 which isadapted to reciprocate in the guides 60, said member being pivotallyconnected to the pitman 62 as at 63, so as to allow for the throw of thecrank 52.

A belt-conveyer 64 is provided for conveying the coal from the forwardend of the machine toward the rear, said belt being mounted on rollers65 and 66. .P'ower for driving said belt is transmitted from the motor58, butras said conveyer-belt forms no'part of my invention, it has notbeen deemed necessary to illustrate or describe the same in detail. Thebelt 63 delivers the coal onto a conveyer-belt 67, and this belt carriesthe coal to the rear to be .delivered into a mine-car. Thisconveyer-belt, however, forms no partof my invention, and has it at thehei 5 is released by the not been illustrated in detail.

hen my improved machine is in use, the

truck 2 is brought up on the track 4 into position for the machine tooperate on the coal, as clearly shown in Fig. 2. The frame hook-latches16 and said frame drops with the casters -15 resting on the mine-floor.Power is then appliedto operate the cutter-chains 41 and these outterscut into the coal across the wall thereof making the cuts at differentheights. Simultaneouslywith this operation of the cutter-chain .4 1 thepicks 59 are put into operation, said picks being inclined at an angleto the wall and Working alternately on the coal above the chain-cutters.The angle at which the picks operate can be changed by raising orlowering the bar 47 and securing ght desired in the clevis 49.

y mountmg the cutter chains on the triangular frames at the front end ofthe maof a frame,

chine, thevchains are very materially reduced in length and less poweris required to operate the same thereby reducing the cos-t ofoperations, and providing a more effective cutting means.

The coal, as it ismined, is deposited on the conveyer 63 and carried tothe rear of the machine.

The frame 5 may be shifted laterally due to the fact that said frame ispivotally mounted on the king-pin 13, and in this way the cut may bemade across the entire Wall of coal. i

What I claim is:

1. In a mining machine, theoombination of a suitable frame, triangularshaped chainguides at the forward end of said frame at differentheights, cutter-chains mounted in said guides, and means for drivingsaid cutter chains.

2 In a mining machine, the combination of a frame, a series oftriangular shaped chain-guides at the forward end of said frame arrangedat different heights, a vertical shaft in said frame passing throughsaid chain-guides, means for driving said shaft, sprocket-wheels mountedin said chain-guides, and cutter-chains engaging said sprocket-wheels.

In a mining machine, the combination of a frame, a series ofcutter-chains carried by said frame at different heights, picks abovesaid cutter-chains, and means for reciprocating said picks.

In a mining machine, the combination of a frame, cutter-chains carriedthereby at different heights, picks above .said cutterchains, means forchanging the angle of said picks, and means for reciprocating saidpicks.

5. In a mining machine, the combination of a frame, cutter-chainscarried thereby, arranged at different heights, picks above said cutterchains, and means for reciprocating said picks, said picksalternatingwith each other in advancing and withdrawing from the coal.

In mining machines, the combination of a frame, a series ofcutter-chains arranged at different heights, means for drawing saidcutter-chains, a pick-frame supported by said frame above saidcutter-chains, said pick-frame having guides therein, picks mounted insaid guides, and means for reciprocating said picks.

In a mining machine, the combination a series of chain-cutters arrangedat different heights, pick-frames supported by said frame above saidcutterframes, picks carried by said pick-frame, means for reciprocatingsaid picks, a rearwardly extending bar connected to said pick-frame,said bar being fulcrumed on vof a frame, a series of cutter-chainsarranged at diflerent heights, a pick-frame on said frame above saidcutterrehains, picks mounted in said frame, a double-crank 4 shaftmounted insaid frame, connections between said picks and said doublecrank 10 shaft, the cranks of said shaft being set at difierent anglesWithreference to eaehiother.

In testimony whereof, I the said WILLIAM E. YOUNG, have hereunto set myhand.
